Change default HASH_KNOWN_HOSTS=false
The original reason for hashing known_hosts was to prevent worms from reading that file to find hosts that can be exploited next. While this is still true, those worms can easily parse the gnupg pubring for ssh://... public keys. So hashing known_hosts does not improve the situation when using monkeysphere. All it does is pretending false security. It should therefore default to false.
